Denver allows residential security cameras without a permit. Colorado is a one-party consent state for audio recording. Video surveillance of publicly visible areas is permitted. Cameras must not intentionally record areas where people have a reasonable expectation of privacy.
Residential security cameras are permitted in Denver without any city permit, registration, or notification requirement. Property owners may install cameras covering their own property and areas visible from public vantage points. Colorado is a one-party consent state under CRS 18-9-303, meaning only one party to a conversation needs to consent to audio recording. This makes doorbell cameras and security cameras with audio features easier to use legally compared to two-party consent states. However, cameras must not intentionally record areas where individuals have a reasonable expectation of privacy, such as inside a neighbor's home, bathrooms, or bedrooms. Video-only surveillance of publicly visible areas (sidewalks, driveways, front yards) does not require any consent. Denver does not require signage for residential security cameras, though posting notice is considered best practice. Colorado's eavesdropping statute (CRS 18-9-304) prohibits the use of electronic devices to listen to or record conversations without at least one party's consent. Violating eavesdropping laws is a class 6 felony.
Eavesdropping (recording without any party's consent): class 6 felony under CRS 18-9-304. Civil liability for invasion of privacy.
